Do you run into any problems with the lack of EMI/RFI shielding?

Nothing obvious that I've noticed (like radio voices or anything). I don't have the tools or the knowledge to chase the less obvious manifestations of RFI. The worst RFI problems I had was when I was building my phono stage - buzzing, crackling, and Spanish talk radio.

Line a wood box with copper foil available at craft/hobby shops, and you are better off that any steel box for RFI. And you can solder a wire from it to ground. Steel boxes are prone to bad connections to the ground, since you are generally using a screw on connection.

How about an attache case? You could have all the tube sticking out of the lid just like every other kit, but anytime you wanted to work on it, or show off the insides, just open the lid. The bonus is a built in handle for packing it around. You could have plastic, vinyl, leather, or even high tech aluminum.

i had a friend in college who carried an acrylic 'briefcase'.

an artist's paint box is essentially a wooden briefcase. they look nice too.

if you have a 'container store' nearby there's lots of good box ideas in that shop.

(FWIW - there's a popular headphone amp project on www.headwize.com that many people (myself included) have chosen to build in an altoids tin. for a fullsize amp you could use a larger cookie or candy tin. circular, even.)

yesterday, i spotted a coca-cola metal tray that might look good hanging from the wall with tubes spouting from it , ..assuming of course that it is securely mounted, ... i don't know how this fits into the vibration dampening scheme of things, but anyway ....

methinks the ultimate cool preamp would be built into one of those short stout minikeg aluminium cans of beer. not the easiest space to work in, but it just might be possible.

Ikea. Cheap. Wood. Stylish.

:)ensen.

Oops. Hit enter too quickly.

Ikea also as many metal storage boxes. You could use the mesh office supply stuff and have passive surround cooling.

Yeah, the wastepaper baskets will become excellent drums for a BBQ coffee roaster. Ooops, wrong forum, sorry
Also, letīs not forget the shelf itself. With a stereo rack/shelf system that has removable shelfs, you could simply mount the stuff directly on the shelf - or if it is an inappropriate shelf material, just make a replacement shelf yourself in which you may drill and mount to your hearts content. I am thinking of John Sherwoods amps (the picture at the bottom of the page), that one looks great I think, but I would probably use one or two of the shelves in my "rack" instead. Nice copper tubing though!
